| Subject: CVE-2024-41019: fs/ntfs3: Validate ff offset |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| fs/ntfs3: Validate ff offset |
| |
| This adds sanity checks for ff offset. There is a check |
| on rt->first_free at first, but walking through by ff |
| without any check. If the second ff is a large offset. |
| We may encounter an out-of-bound read. |
| |
| The Linux kernel CVE team has assigned CVE-2024-41019 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
